Synopsis

Description

CREATE USER MAPPING defines a mapping
of a user to a foreign server. A user mapping typically
encapsulates connection information that a foreign-data wrapper
uses together with the information encapsulated by a foreign
server to access an external data resource.

The owner of a foreign server can create user mappings for
that server for any user. Also, a user can create a user mapping
for his own user name if USAGE privilege
on the server has been granted to the user.

Parameters

user_name

The name of an existing user that is mapped to foreign
server. CURRENT_USER and
USER match the name of the current
user. When PUBLIC is specified, a
so-called public mapping is created that is used when no
user-specific mapping is applicable.

server_name

The name of an existing server for which the user
mapping is to be created.

OPTIONS ( option 'value' [, ... ] )

This clause specifies the options of the user mapping.
The options typically define the actual user name and
password of the mapping. Option names must be unique. The
allowed option names and values are specific to the
server's foreign-data wrapper.
